What is 8.5 percent of 830 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 830 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 830 is 100%, so we can write it down as 830=100%.
4. We know, that x is 8.5% of the output value, so we can write it down as x=8.5%.
5. Now we have two simple equations:
1) 830=100%
2) x=8.5%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
830/x=100%/8.5%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 8.5% of 830

830/x=100/8.5
(830/x)*x=(100/8.5)*x       - we multiply both sides of the equation by x
830=11.764705882353*x       - we divide both sides of the equation by (11.764705882353) to get x
830/11.764705882353=x
70.55=x
x=70.55

now we have:
8.5% of 830=70.55
